In the following guide I show how to remove and replace the LCD screen on a HP G42 or Compaq Presario CQ42 laptop.
In this particular case I’m removing screen from a HP G42-303DX laptop.
In order to replace the LCD screen it’s necessary to separate the display panel from the laptop base first. Otherwise you will not be able to remove the screen bezel. Check out my first HP G42 and Compaq Presario CQ42 disassembly guide for the display panel removal instructions (steps 1-27).
OK, let’s assume the display pane has been removed and now we can start taking it apart.
Remove the screw cover from the lower right corner of the screen bezel.
Remove the screw.
Remove the screw cover from the lower left corner of the screen bezel.
Remove the screw.
Start separating the screen bezel from the display back cover. I’m doing that with the guitar pick. You can use a piece of plastic.
Insert the guitar pick between the bezel and back cover and slowly move it along the side. At the same time wiggle the screen bezel to unlock it from the back cover. There are small hidden latches securing the bezel.
Continue separating the bezel with your fingers.
You’ll have to apply some reasonable force to lift up the bezel because it’s glued to the LCD screen with sticky tape.
Separate the bezel on the upper side of the display and than move to the lower part.
Remove the screen bezel.
Remove two screws securing the display hinge covers.
Lift up and remove both hinge covers.
Remove six screws securing the LCD screen assembly.
Separate the LCD screen from the display back cover and place the screen face down on the table.
Now you can access the video cable on the back of the screen.
Unglue the clear tape securing the connection.
Unplug the video cable connector from the LCD screen.
Remove the LCD screen assembly.
Now the screen is ready for the replacement.
Remove two screws securing the screen mounting bracket to the right side of the screen.
Remove the screen mounting bracket and transfer it to the new LCD screen.
Do the same with the bracket attached to the left side.
